The .jacketgl of the cariister isflprovided With ablur'ality cf longitudinal slits 7, pref- .erabl symmetrically arranged, as shown:

In use, the spacing members 6, as is evi' dent, prevent the usual wedging action, Which, in other constructions, takes plaCebe-' tween the halls, due to the"setback of discharge. The spacing members also preyent the scoring of the bore of a gun, which takes place with canistejrs not provided with such spacing members, and thus;theenergy consumed in batteringthebore in the usual con-' struction of.,ctnisters is saved, thus increas ing the longitudinal acceleration, and fsecur* ing a higher inuzzle velocity and, consequently, a mi1chgreater strikin'g' velocity and B37 the Weakened con 1 of th,- jacket 1, it results 'that the tendency strctioh, as described,
